Information On Cheap Razor Blades

By Deborah Anderson

A razor is a bladed tool that people use to shave hair from various parts of the body. There is evidence indicating that razors were in existence before the Bronze Age. Obsidian and bronze were the major materials used to make these tools in most ancient worlds. They were oval-shaped with tangs protruding from the short end. The ordinary razors in use today were invented in the eighteenth century, with electric models coming up in the 1960s.

These products have evolved a lot because of technological advancements. The modern market has a lot of cheap razor blades one can pick from. Some great examples of these products are electric razors, straight razors, and disposable razors. The invention of the various types of razors occurred at different times and they have also evolved differently into what they are today.

Straight razors were the dominant types of razors in use before the advent of the 20th century. Cut-throats is the other name for straight razors. They consist of handled with a single sharpened edge. Carbon steel and stainless steel are the two most commonly used material in making them. Stainless steel blades are durable but hone and strop more slowly. Conversely, carbon steel blade hones and strops faster but does not last long.

Producers still make both stainless steel and carbon steel blades. However, stainless steel blades are harder to find. These razors rotate between two protective scales on a pin. The scales exist to protect the blade from damage and the skin from cuts when the device is folded. Handle scales are made from various materials, including celluloid, plastic, bone, mother-of-pearl, and wood. Ivory was once in use, but its use was stopped.

Disposable blade straight razors look like straight razors and are used in the same way. The main difference is that razors are disposed after use. They may be designed to use a single-edged blade or double-edged blade. These varieties do not require honing or stropping. The razors are prone to wearing out fast. The useful life of blades can be prolonged by providing proper care such as cleaning and drying well when not in use.

Safety razors protect the skin from all parts of the tool, except the edge. It was invented by a Frenchman named Jean-Jacques Perret in 1762. The design resembles straight razors only that the blade has wooden sleeves surrounding it. Modern varieties have safety bars included to protect the skin from cuts. Two main types of safety razors exist, that is, double-edged and single-edged.

Electric razors also go by the name electric dry shavers. These models have an integral oscillating or rotating blade. They run on tiny DC motors, which derive their power from either batteries or electrical energy from the mains. Water, shaving cream, and soap are not necessary when using these devices.

Invention has led to the development of new electric razors that rely on rechargeable batteries for power. Rechargeable batteries may be alternated with electro-mechanical oscillators that are driven by AC-energized solenoids. The oldest models of electric razors were powered by hand. Flywheels in the devices were driven by pulling a cord by hand.
